Clustering is one of the main data mining techniques used to divide the data into several groups and each group is called a cluster, which contains objects that are homogeneous in one cluster and different from other clusters. As a reason of many application that depend on clustering techniques, and since there is no combined method for clustering, this paper focus on the comparison between k-mean, Fuzzy c-mean, self organizing map (SOM) and support vector clustering (SVC) to show how those algorithms solve the clustering problem, compare the new methods of clustering (SVC) with the traditional clustering methods (K-mean, fuzzy c-mean and SOM), and show how the studies improve SVC algorithm. The results shows that SVC is better than the k-mean, fuzzy c-mean and SOM; because it has no dependency on either the number or shape of the cluster, it can deal with outlier, ...

Different managerial and academic departments at Al- Quds Open University (QOU) achieve their work using different types of information systems; such as admission IS, Registration IS, Students affair IS, HRM IS, Procurement IS, in addition to the academic portal that used to achieve different academic duties. Therefore the main objective of this study is to provide a further insight into IS effectiveness and test this effectiveness at Al Quds Open University. This study uses the Delone and Mclean model and its instrument to measure the information systems dimensions which include six constructs mainly system quality, information quality, service quality, system usefulness, user satisfaction, and net benefits. All QOU branches and centers have been investigated in the West Bank- Palestine (87) surveys were collected from the QOU pre...

Therefore; innovative ways are required for using information systems. Information systems (IS) specialists’ sub-culture is an important determinant of information systems success that not deeply discussed by researchers. Thus a comprehensive understanding of information systems success remains fuzzy and elusive in this area. Therefore, the main objective of this study is to provide a further insight into IS specialists sub-culture. In an attempt to address this situation, this study use an adapted instrument for measuring the IS specialists sub-culture, which includes eight constructs. Palestinian financial institutions have been investigated; which includes (39) institution, consists of banks, insurance companies, financial market, where (66) surveys were collected from the IS specialists in those institutions. The main findings of this study show that IS specialists have a clear culture; which characterized with ...

However, empirical results in this area are inconsistent, and an overall synthesis across the numerous empirical studies seems lacking. The main objective of this study is to find the most important design factors that attract users, predict affective design, and develop a model that enables the evaluation of design factors along with the core affect. The main finding of this study is that design factors varies in their impact on core affect, where the empirical evidence supports the impact of text's font-size, menu direction, fore-color have on users core affect, the other design factors including menu location and alignment, back-color, icons type and size, and font type and alignment doesn't have significant impact. Therefore the study adds to the literature on design factors that needs more emphasis.

While information technology platform effects the organizations ability to enjoy its business plans, through restricting the reach and range of its information. The main objective of this study is to provide a further insight in to the interorganizational systems platforms, and its impact on data sharing, and then find out the platform that most suites the organizational requirements. A comparison between electronic data interchange (EDI), and web services were conducted and then matching the results with the information reach and range. The main findings show that; the Web services platform can take place when the range of information access is required by anyone and anywhere regardless of IT base. EDI can take place when the range of information access doesn’t exceed the organizations boundaries. But when the range of information access exceeds the organizations b...

The main objective of this study is to provide a further insight in to IS success, develop measurement tools for IS success, and then, test the (D&M) model to ensure its validity and explanations to IS success factors. In order to test the research hypotheses, data were collected from IS end users (respondents) in Palestinian Financial Institutions using a proposed questionnaire. 189 usable surveys were used in data analysis. After that, construct validity and the internal consistency reliability of the measures were tested, using Coronbach's Alpha test. The results show high reliability of all used measures, where Coronbach's Alpha exceeds 0.7. Hypothesis embedded in the research model were tested using correlation, regression, a...

However; there is no distinct way to conduct such evaluation, because; the most used theories and models depends on two different approaches, mainly; behavioral theories, and information based theories, therefore, the evaluation process remains fuzzy and elusive. This study aims to review information systems success theories and models; in order to compare and evaluate those theories and models, for the purpose of integrating the results with the perevious studies in this area, and to find out a unified model for evaluating information systems success. To achieve these objectives, the current study reviews literature related to information systems success theories and models, where the most used theories and models are the theory of reasoned action, theory of planned behavior, technology acceptance model, Delone and Mclean model (D&M), Seddon Model. After that a comparison between the testin...

This area wasn’t discussed deeply by researchers. Thus a comprehensive understanding of information systems remains fuzzy and elusive in this area. In an attempt to address this situation a comprehensive model was developed. Although this model is not empirically tested, it tries to explain the impact of organizational politics forms (avoiding, competing, accommodating, compromising, and collaborative) on the information systems success dimensions (system quality, information quality, service quality, use, user satisfaction, and net benefits).
